Abstract
PURPOSE:To prevent the belt from being locally damaged, by applying a reciprocating motion to a square shape case of the wristwatch with a shifting amount less than a width of the grinding belt, and processing a work of grinding the case with surfaces of the grinding belt fully utilized. CONSTITUTION:A grinding belt drive mechanism unit 1 comprises a drive mechanism 39, that rotates two grinding belts A, B of different grain size with an electric motor M1 being the common drive source. And a case drive mechanism unit 2 comprises a work holder 3, consisting of a work holder shaft 11, a work chuck 12, etc., a mechansim 4, for inversely rotating this work holder 3, a mechanism 5, for making a work of the work holder 3, that is, a square shape case 9 of the wristwatch reciprocated between belt width in order to effectively use the belt width of the grinding belt A, B, a mechanism 6, for shifting the work holder 3 between the grinding belt A and B, and a mechanism 7, for shifting a table 21 in order to make the work 9 contacted to the grinding belt at the time of processing. Each mechansim in each drive mechanism unit is operated by a controller 8 in accordance with a work shape, and a barrel side of the work 9 is automatically processed grinding.
